      The expectation is that these tags will not be understood as a node alone, but together with
      the parent node.

      <br />

      But for block-level elements, it will be understood as a separate node
      <div>
        this is a
        <b>div</b>
        element
      </div>
      <p>
        this is a
        <b>p</b>
        element
      </p>
      <h1>this is a h1 element</h1>
      <ul>
        <li>this is a li element</li>
      </ul>
      <dl>
        <dt>this is a dt element</dt>
        <dd>this is a dd element</dd>
      </dl>

      <br />

      There are also some special tags, such as
      <b>br</b>
      ,
      <b>hr</b>
      should also be understood as a sign of the end of a paragraph. here is a br tag:
      <br />
      here is a hr tag:
      <hr />
      They will both be understood as the end of a paragraph.
